The Dell Precision T7910 is a workstation featuring an EATX motherboard with Dual LGA2011-3 sockets. This server supports Xeon E5-2600 v3 in dual processor configurations and Xeon E5-1600 v3 in single processor configurations. If the BIOS revision is A12 or newer then it will also support dual Xeon E5-2600 v4's or a single Xeon E5-1600 v4. This workstation uses a C612 chipset. It features 16 DIMM slots and can accept DDR4 LRDIMMs up to 64GB/stick for a total of 1TB in a dual processor configuration or RDIMMs up to 32GB/stick or a total of 512GB in a dual processor configuration. With a single processor configuration that number is halved. This may eventually be increased to officially support 128GB LRDIMMs but that has not been confirmed yet.

The T7910 features 6 x16 width PCIe slots and one PCI slot. The top two PCIe slots are linked to processor 1 and the bottom 5 slots are linked to processor 0. This means that if you do not have a second processor in then the top PCIe slots will not be operational.

This workstation can house 4 hot swappable 3.5" drives in the front or up to 8 2.5" drives. The processor socket is square ILM if you are looking for a heatsink replacement.

The Dell Precision T7600 is a workstation featuring an EATX motherboard with dual LGA 2011 Sockets. These only currently support the E5-2600 first generation processors, but it has the same chipset as the T7610 which received support for the second generation processors so it seems they may soon get support if Dell puts out a BIOS update. The system has 16 DDR3 slots with support for up to 16GB RDIMMs or 32GB LRDIMMs. The T7610 received support for 64GB LRDIMMs so it seems that if the T7600 does get the update for the second generation E5 processors then the 64GB LRDIMM support may come with that update as well. The workstation features 4 hot-swappable bays that can easily accommodate either 3.5" or 2.5" drives of either SAS/SATA. The system comes standard with a PERC H310 RAID controller to handle the hardware RAID configuration.

The Precision T7600 has 5 PCIe slots available if you are only utilizing a one-processor configuration but adds two more PCIe slots if you add in a second processor. All slots are full-height, full-width, but the first and the third slot under the processors only operate at x4 speed instead of the full x16. The workstation features dual gigabit networking ports with Intel adapters: 82574L and 82579LM. The maximum capacity of a single processor configuration with RDIMMs is 128GB and with LRDIMMs 256GB. In a dual processor configuration, the maximum addressable capacity is 256GB with RDIMMs and 512GB with LRDIMMs. Maximum single stick capacity is 16GB RDIMMs or 32GB LRDIMMs.

The Precision T7600 has a few known issues that have been addressed with BIOS updates:

The Dell PowerEdge T630 is a Tower based server that has the ability to be converted into a rackmount server when a mounting bracket and rails are installed. It features a proprietary Dell motherboard which is run by an Intel C612 series chipset (Desktop Similar is the X99 Chipset). This allows for dual Haswell-EP (E5-2600 v3 series) processors or Broadwell (E5-2600 v4 series) processors (If BIOS revision 2.1.5 or newer is installed) and 24 slots for DDR4 RDIMMs or LRDIMMs

When running BIOS revision 2.1.5 or newer the maximum addressable memory for a single socket configuration is 1536GB with Quad or Octo Rank Load-Reduced DIMMs. With a dual processor configuration, this figure is doubled to 3072GB. This is using 24 of the recently released 128GB LRDIMMs. If using a revision older than 2.1.5 then the maximum addressable will be 768GB in a single socket configuration or 1536GB in a dual socket configuration. This is achieved using 24 64GB LRDIMMs. Of note, you cannot utilize 128GB DIMMs until the BIOS is updated and you may not use the memory slots assigned to a non-populated processor. To explain further, you cannot achieve the 768GB single processor maximum by using 24 32GB DIMMs because 12 of the slots are associated with the empty processor socket. The memory can operate at 2400MT/s in all configurations and ranks except for triple channel configurations. With RDIMMs the maximum then becomes 1866MT/s in triple channel and LRDIMMs can still operate at 2133MT/s in triple channel

There are many storage configurations for the Dell PowerEdge T630. One option is 32 2.5" drives without the flexbay or 18 2.5" with the flexbay. Another option is 18 3.5" drives without the flexbay or 8 with the flexbay. The flexbay is essentially a riser card that allows the install of PCIe SSD cards in the front or additional hard drives or solid state drives.

There are a few known issues with the T630 that have been addressed with BIOS updates. The most major being users experiencing the red screen of death (RSOD) when using the E5-2603 or E5-2609 processors and performing a reboot. This was remedied in BIOS revision 2.1.5 so if you are using this configuration it is highly recommended you upgrade.
